An attempt has been made towards the synthesis of strongly adherent orthophenylenediamine (OPD) coating on mild steel substrates, with an objective of using the OPD for corrosion protection of steel in hydrochloric acid medium. In this work, the OPD coatings were obtained by electrochemical reduction of orthonitroanil…
This paper is devoted to the study of the effect of the texture, phase composition, and microstructure on the irradiation-induced growth strain (GS) of zirconium-based alloys. GS measurements and TEM microstructural examinations were performed on Zry-2, NSF, and E635 samples in the recrystallized, beta quenched and co…
象 Nd2Fe14B 和 Sm 公司那样的稀土元素的 intermetallics 广泛地被用作高效的永久磁铁，因为他们把高 magnetocrystalline anisotropy 与合理磁化和居里温度相结合。anisotropy 是纺纱轨道联合和静电的水晶地相互作用的联合效果。主要贡献来自稀土元素的 4f 电子，它从水晶的环境是屏蔽得好的，但是展出联合的一条强壮的纺纱轨道。在这限制， magnetocrystalline anisotropy 有很透明的物理解释，实质上等于水晶领域里的 Hund's-rules 4f 离子的精力的 anisotropy 精力。为低顺序的单轴的 anisotropy 常数 K1 的相应表示被用…
Cadmium Zinc sulfide (CdZnS) thin films have been deposited on to ultrasonically cleaned glass substrates with various Zn 2+ concentrations by Micro wave assistedChemical Bath Deposition (Mwave-CBD) technique. The structural studies were carried out by using X-ray diffraction (XRD) studies as a function of Zn 2+ conce…
Water soluble porphyrins were designed and prepared by Williamson ether synthesis reaction between tetrakis(p-bromomethylphenyl)porphyrin and polyethylene glycol (PEG) for photodynamic therapy. The quantum yields for the generation of singlet oxygen of tetra-polyethylene glycol branched porphyrin shows above 80% in D2…
Heat protection and moisture comfort are important for firefighter protective clothing. In this study, the thermal protective performance (TPP) and water vapour transmission rate (WVTR) were measured for 16 assemblies. It was established that outer heat resistant fabric and the moisture barrier have significant effect…
Europium(III) complexes of N-acyl-DL-alaninates (acyl=acetyl, butanoyl, hexanoyl, octanoyl, decanoyl, dodecanoyl and tetradecanoyl), N-octanoyl-DL-phenylalaninate, and N-octanoyl-L-serinate were prepared to understand the effects of alkyl chain length and the type of head group on the formation of glassy states and on…
The reliability of lanthanide luminescence measurements, by both flow cytometry and digital microscopy, would be enhanced by the availability of narrowband emitting, UV excited lanthanide calibration beads. 0.5-, 3-, and 5-microm beads containing a luminescent europium-complex are manufactured. The luminescence distri…
Self-assembly of lyotropic liquid crystalline mesophases formed by amphiphilic molecules was studied using computer simulations. The addition of an inorganic and two hybrid organic–inorganic precursors, one with a bridging and the other with a terminal organic functionality, lead to the formation of bifunctional hexag…
The effect of application alternating current on the modification of primary Mg2Si crystals in the hypereutectic Mg-4.8 mass%Si alloy has been investigated in the present study. The liquidus and eutectic temperatures of the Mg-4.8 mass%Si alloy are 761°C and 638°C, respectively. An alternating current of 60 A with fre…
Chalcogenides based non-volatile memory is a promising type of non-volatile memory that display several advantages over the currently wide spread flash memory. This paper reviews the theory, fabrication and operation of two types of chalcogenide based non-volatile memories, i.e. phase change memory (PCM) and programma…
Influence of Annealing on Europium Photoexcitation Doped into Nanocrystalline Titania Film Prepared by Magnetron Sputtering, Podhorodecki, A., Zatryb, G., Misiewicz, J., Domaradzki, J., Kaczmarek, D., Borkowska, A.
Superhydorphilic polyester film has been obtained by oxygen plasma treatment to maintain optical clarity under high relative humidity. The original and treated films are simultaneously exposed to the vapor from hot water. The latter keeps its optical clarity because the condensed water formed a thin film on it instead…
Nowadays, transformers are made of conventional magnetic cores which are constructed of a single grainoriented or amorphous, magnetic steel. Even though, the transformer is the most efficient of electrical machines, with efficiencies typically above 90%, it is possible to improve transformer performance by using compo…
The X-ray single-crystal structure of methyl 2-aminoisobutyrate hydrochloride (Me-AIB), a non-standard amino acid, is reported at 10, 30, 50, 70 and 100 K. Fourier maps indicate the presence of rotational disorder of the hydrogen atoms of the ester methyl group. To study this effect in detail, high resolution data wer…
Highly oriented, Bi-substituted Ca3Co4O9(Ca2.7Bi0.3Co4O9) was processed by the rolling method and its thermoelectric properties were investigated. The electrical conductivity (σ), Seebeck coefficient (α), thermal conductivity (k) and ZT value at 870 K were 123.4 S/cm, 172.7 μV/K, 2.1 W/mK, and 0.152, respectively. The…
The dynamic hardness of rutile TiO(2) single crystal surfaces was investigated using a nanoindentation technique and the hardness increase was observed only in the near-surface region, possibly due to the volume expansion accompanied by the photoinduced high hydrophilicity.
10 wt% Gd2 O3-dispersed UO2 pellets, in which Gd2 O3 particles are dispersed in UO2 matrix, were prepared, and the thermal conductivity was investigated. The Gd2 O3-dispersed UO2 pellets consisted of Gd2 O3, UO2, and a Gd—U—O phase that was formed by diffusion of U ions into Gd2 O3 particles during the sintering proce…
In the present work, the effect of surface treatment methods on the henequen fiber topography and how the surface treatment influences the interfacial shear strength of henequen/unsaturated polyester composites were studied. Two different surface treatment methods were used: soaking method and ultrasonic method. Two d…
